On boundary avoiding selections and some extension theorems [PDF]

open access: yesPacific Journal of Mathematics, 2002
It is proved that the following conditions are equivalent: (i) \(X\) is normal and countably paracompact; (ii) For every convex subset \(C\) of a separable Banach space \(B\), every lsc multifunction \(F: X\to C\) with values convex and compact in \(B\) and every \(F_\sigma\)-subset of \(X\) contains in \(F^-(\text{Int\,}C)\) there exists a continuous ...

A New Measure for the Tendency to Select Ideologically Congruent Political Information: Scale Development and Validation

open access: yesInternational Journal of Communication, 2016
Selective exposure is a popular research construct, but the strategies used to operationalize ideologically congruent exposure in contemporary correlational research are problematic.

Range Sensor-Based Efficient Obstacle Avoidance through Selective Decision-Making

open access: yesSensors, 2018
In this paper, we address a collision avoidance method for mobile robots. Many conventional obstacle avoidance methods have been focused solely on avoiding obstacles. However, this can cause instability when passing through a narrow passage, and can also

Avoiding the Other Side? [PDF]

open access: yesJournal of Media Psychology, 2020
Abstract. Partisan selective exposure, the phenomenon of selectively attending to information that is in line with one’s political views, has received extensive research attention. Researchers have thus far largely neglected, however, to examine the tendency to avoid attitude-discrepant information, that is, selective avoidance.

Protocadherin-dependent dendritic self-avoidance regulates neural connectivity and circuit function

open access: yeseLife, 2015
Dendritic and axonal arbors of many neuronal types exhibit self-avoidance, in which branches repel each other. In some cases, these neurites interact with those of neighboring neurons, a phenomenon called self/non-self discrimination.

Selective Avoidance on Social Media: A Comparative Study of Western Democracies

open access: yesSocial Science Computer Review, 2021
This study examines the phenomena of political unfriending and content removal on social media in three Western democracies—France, the United Kingdom, and the United States. We seek to understand the role of crosscutting discussion, confrontational discussion style, and ideological extremity in triggering unfriending and content removal on social ...

Signaled two-way avoidance learning using electrical stimulation of the inferior colliculus as negative reinforcement: effects of visual and auditory cues as warning stimuli

open access: yesBrazilian Journal of Medical and Biological Research, 1998
The inferior colliculus is a primary relay for the processing of auditory information in the brainstem. The inferior colliculus is also part of the so-called brain aversion system as animals learn to switch off the electrical stimulation of this ...

From Selective Exposure to Selective Information Processing: A Motivated Reasoning Approach

open access: yesMedia and Communication, 2019
Literature suggests that while without doubt people engage in selective exposure to information, this does not entail that they also engage in selective avoidance of opinion-challenging information. However, cross-cutting exposure does not always lead to

Imaging of High‐Risk Neuroblastoma: Recommendations From SIOPEN Radiology and Nuclear Medicine Specialty Committees

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Neuroblastoma is the most common extracranial solid tumor in early childhood. Its clinical behavior is highly variable, ranging from spontaneous regression to fatal outcome despite intensive treatment. The International Society of Pediatric Oncology Europe Neuroblastoma Group (SIOPEN) Radiology and Nuclear Medicine Specialty Committees ...
